After Installing Lion how do i get the windows partition back?

Oh please.... Ever heard of backups?

For those who hasn't reinstalled the Windows partition, there are 2 things might be worth trying (not saying that it will fix the problem 😝)

1. See if there is error on your Lion Volume

I gave in last night and decided to reparation my drive. That led me to discover that my Lion Volume has errors. So I booted into Recovery HD and ran a repair in Disk Utility from there. At the end of the repair log it says something like "updating other boot volumes as required". But this happened after I have restored the HD to be a single volume.

2. Upated the file system extension software if you have one.

Another discovery that I had is that I have MacFuse installed. And it's 32 bit. After I repartitioned the drive and installed Windows, the Windows partition still showed up at disk04 and wasn't mountable in Disk Utility. After I installed the 64bit version of MacFuse, things seemed to be back to normal, for now...

Guys, in order to remove the restore partition, read the following page:

Make sure you've got a working and verified backup before messing around

The 200 Mb partition is the "System Reserved" partition of windows, which only will be created by the enterprise and Ultimate version. Its purpose is for support of Bitlocker and a few other features of windows 7, which you most likely will not use.

The 400 Mb, is the real killer... Unless you made a backup, your scr**ed.

For next time, there is a backup utility in Windows 7 that let you make a kind of an image, which you can fully restore. But that does not help you.

But, I am surprised MacOS took the space of the restore partition of Windows.

On my Mac, it took 650 Mb from the MacOS partition.

I have a question. The other day, my brother installed the new Mac OS X 10.7 Lion on my MacBook, and my Windows Partition doesn't boot anymore...Do you think there's a way I can get it back? I'm not sure if it's completely gone...But I had a lot of videos and other important stuff that was on there...It says "disk0s4" and it's not mounted...

And I see that you mentioned that Windows deleted/overwrite the first 600MB of the Windows Partition. And to be honest, that's fine with me. I have sooo many videos, pictures, and important files on my Windows Partition. I'd be happy to get at least some of it back. If you have any answers, then please let me know. Thanks.

My brother said that he's going to take the hard drive out of my MacBook Pro and try to use it on a Windows computer...Do you think it'll read?! Thanks.

Perhaps, perhaps not hard to say...

From a logical point of view, I am bound to say that everything is lost. At the same time, it might well be that, once booted in windows, the partition will show up.

There is not a good explanation for that, but I have seen it happening that a partition that doesnot exist in Windows (unused space) is an actual partition in Mac, and a partition deleted in Windows still shows up and is usable in Mac.

However this is the other way around, and usually it is Mac that is leading, which means that when Mac OS is repartitioning the HD it is really doing so,if you get my point.

One question, why is nobody making any backups before installing a new OS? Isn't that rule number one?

Cheers

I do not believe Apple has provided official backup steps and software for the BootCamp partition in spite of the fact that they offer BootCamp as an official feature. Time Machine is offered as a backup mechanism for Mac OS partitions. To my knowledge, this is the first time Apple has attempted to insert a new partition as part of an OS upgrade. For whatever reason, there was an assumption that this would be a safe operation and no warning was provided.

The only reason I had partition level backups was because I upgraded my system hard drive. While it is the end users responsibility to have backups, my impression is that Apple consumer level systems have been developed assuming a not very experience computer user will probably be using the system.

Please review this thread. I believe at least one user has had some luck booting the Mac with the Windows installation CD/DVD and attempting to repair the damaged partition.

Windows does provide a baclup system by itself. You would need a NTFS formatted USB drive in order to make use of that feature.

In a way it works like the Time Machine Backup program.

I had no idea that updating to Lion OS X would affect my Windows Partition...But I took a screen shot of what it says in Disk Utility...

What do you think?!

For me OS X Lion is the Windows Vista of Apple systems. The more you use it, the more you hate it.

Anyway, I gave up trying to recover my Win 7 partition. I just want to ask if anybody figured out a way how to rescue some single files from the Win partition corrupted by Lion? Any ideas?
